Section 1:ADT-LCD40 Series Annunciators
Note: Only Model ADT-LCD40L is listed for use in Canada.
The ADT-LCD40 Series Annunciators are compact, attractive,
40-character, backlit LCD fire annunciators designed for use with the
Unimode 200 Addressable Fire Alarm Control Panel. The
ADT-LCD40L operates the same as the ADT-LCD40, except it does not
have function switches or a key-switch. It should be noted that the
ADT-LCD40 Series Annunciator displays will mimic the LCD display
located on the Unimode 200 main circuit board.
If software with Part Number #UNIMODE200V3.0 is installed in the
ADT Unimode 200, the ADT-LCD40 Series Annunciator must have soft-
ware with a Part Number of 73879 to operate with the control panel. If
software with a Part Number of #UNIMODE200V4.0 or higher is
installed in the Unimode 200, the ADT-LCD40 Series Annunciator must
have software with a Part Number of #LCD40V2.0 or higher to operate
with the control panel.
The ADT-LCD40 Series is capable of displaying English-language text
of system point status including device type, independent point alarm,
trouble or supervisory, zone and custom alpha labels programmed into
the control panel. The ADT-LCD40 Series also provide system status
LEDs to display Power, Alarm, Trouble and Supervisory conditions.
The ADT-LCD40 is capable of performing system acknowledge,
silence, drill and reset remotely while the ADT-LCD40L does not have
these features.
Communication between the control panel and the ADT-LCD40 Series
is accomplished over a two-wire serial interface employing the EIA-485
communication standard. Up to 32 annunciators may be connected to
the two-wire EIA-485 circuit. The annunciators may be powered from
the host FACP or remote UL listed, filtered, power supplies.
